I think I have SIBO also, although I haven’t been diagnosed. I’m pretty sure I do though. I can taste hydrogen peroxide in my mouth, and I have frequent belching, almost constant bloating, and I can barely eat. I’ve been reading about it online, and there are some articles on the National Institutes of Health webpage that say that oil of oregano can be as effective, and in some cases even more effective than an antibiotic. Maybe you could try that? I think I’m going to try it. I don’t know what else to do. Good luck!
